"Big Ben" is the world's most famous misnomer. Technically, it's the 13.7-tonne Great Bell inside the Elizabeth Tower (renamed 2012 for Diamond Jubilee). Colloquially, it's the entire clock tower of the Palace of Westminster.
Likely named for Sir Benjamin Hall (First Commissioner of Works, 1855-1858)—a large man, "Big Ben." Alternative: champion boxer Benjamin Caunt. First struck July 11, 1859. Cracked two months later (hammer too heavy). Repaired, rotated, lighter hammer—distinctive tone persists.
£80M conservation: clock mechanism dismantled, tower cleaned/repointed, waterproofing, lift installed, original Prussian blue/cream colors restored. Silent 5 years (except Remembrance, New Year).
BBC time signal (1924-). New Year broadcast. "Big Ben" = London = UK = democracy's heartbeat. UNESCO World Heritage (Palace of Westminster). Most Instagramed UK landmark.
It's a bell. It's a clock. It's a tower. It's a symbol. The name drifted upward—from bell to clock to tower to nation. That's what icons do.
